SprintRay's New Ceramic Resin Can 3D Print Dental Crowns in 10 Minutes

SprintRay is claiming a real shift in digital dentistry. The company has launched Midas Restore, an FDA-cleared ceramic and zirconia-filled resin designed specifically for its Midas Digital Press. The material can print up to three definitive crowns in roughly ten minutes, which is faster than the typical milling cycle for the same restorations.

The key is the process behind it. SprintRay calls it Digital Press Stereolithography, or DPS. Instead of relying on conventional vat photopolymerization, the Midas system uses hydrodynamic principles to push highly viscous resin into the print zone. That lets Midas Restore carry a filler load over 75 percent by weight without sacrificing accuracy. Conventional dental 3D printers cannot process a material that thick.

The resin itself combines glass ceramic and zirconia fillers. SprintRay says the resulting restoration flexes more like dentin than like traditional glass ceramic, so once bonded to the remaining tooth structure, stress distributes across both material and tooth rather than concentrating at the bond line. In lab testing, Midas Restore retained 98 percent of its initial gloss after 5,000 simulated toothbrush abrasion cycles and delivered five times the wear resistance of SprintRay's previous Ceramic Crown material over 200,000 cycles. Biaxial flexural strength reached 215 MPa, the highest SprintRay has recorded for a definitive restorative material.

Same-visit dentistry has been the promise of digital workflows for years, but most labs still send out designs for milling or require multi-day print jobs. SprintRay is positioning Midas Restore as a way to close that loop entirely in-office: print the crown, post-cure for four minutes, polish with two wheels in under two minutes, no glaze oven required.

The material launches September 1, 2026 in the United States in five shades: A1, A2, A3, B1, and C2. A three-pack of single-unit capsules costs $135 through the SprintRay Store and authorized distributors. The FDA clearance covers the K260661 510(k) as a Class II, prescription-only device.

This matters because dentistry has been waiting for a printable definitive material that does not feel like a compromise. Resin crowns have traditionally been weaker or less aesthetic than milled ceramics. Midas Restore attempts to meet both demands in a workflow that competes with the turnaround time of a lab but keeps the entire process in the operatory.
